Q:What is the difference between construction non-vulcanized waterproofing membrane and vulcanized waterproofing membrane?

Non-vulcanized rubber waterproofing membrane: from SR or SR and asphalt blends by mixing, rolling made of coil, without vulcanization can use the product. The bonding between the coils and their bonding properties with the mortar is good, the manufacturing is convenient, the price is low, but the tensile strength is low. Can be divided into two types of rubber and rubber asphalt. Rubber type commonly used SBR and other SR production. Generally used for civil construction roof waterproof.

Q:What is the material on the insulation layer on the waterproofing membrane?

2, waterproof layer on the other construction layer construction, it is possible to pierce the waterproof layer, the appropriate protection Is necessary, the isolation layer can also play a protective role.

Q:Polyethylene polypropylene waterproofing membrane forming. Secondary molding, what does it mean? How to distinguish?

In the appearance and mechanical analysis, these two processes is difficult to distinguish, a composite also has poor quality, the second compound can also be done better. So, only in the approval of the production line, to control.

Q:Whether the polyester waterproofing membrane can be used for roofing waterproofing

3, even if the roof exposed, the sun exposure is no problem, because the membrane waterproof layer above is to do the protective layer, insulation layer, rather than directly waterproof layer set in the open air;

Q:SBS waterproofing membrane sub-class I and II when to use what level to use a secondary level

SBS modified asphalt waterproofing membrane, this coil has a good high temperature performance, can be -25 to +100 ℃ temperature range of use, a higher flexibility and fatigue resistance, and up to 1500% Elongation and strong puncture resistance, tear resistance. Suitable for cold areas, as well as deformation and vibration of large industrial and civil buildings waterproofing works.

Q:Roof SBS waterproofing membrane additional layer needs to be wide

The waterproofing membrane is a curlable sheet-like waterproofing material. Is one of the important varieties of waterproofing materials in construction engineering.
According to the brand classification Construction industry waterproofing membrane mainly Dike waterproof membrane, DuPont waterproofing membrane, Sicon waterproofing membrane, which the first two participating GB chart set.
According to its main waterproof composition material can be divided into asphalt waterproof material, high polymer modified waterproof membrane and synthetic polymer waterproofing membrane (SBC120 polyethylene polypropylene composite membrane) three categories. There are PVC, EVA, PE, ECB and other waterproofing membrane

Q:Why is the top cover of the basement waterproofing? While the floor has to empty shop?

Waterproof construction methods are generally reflected in the construction drawings. If not, please consult the designer. A waterproof, full of sticky. Secondary, sticky or sticky. Construction waterproof with waterproof material. According to each of the different basement waterproofing, the construction team will have its own waterproof concept and specific construction requirements.

Q:Roof SBS waterproofing membrane can not empty shop

Waterproof membrane: waterproofing membrane is mainly used for building walls, roofs, and tunnels, highways, landfills, etc., to resist the external rain, groundwater leakage can be curled into a roll of flexible building materials , As the engineering foundation and the building between the no leakage connection, is the entire project waterproof first barrier, the whole project plays a vital role. The main products are asphalt waterproofing membrane and polymer waterproofing membrane.

First, SBS modified asphalt waterproofing membrane (polyester tire):
Features: The use of polyester felt (filament polyester non-woven) mechanical properties, water resistance, corrosion resistance is also very good; elastic and low temperature performance has improved significantly, the effective range of (-25 ~ 100) ℃; Excellent fatigue resistance.
Use: for high-level and high-rise buildings of the roof of the single-layer laying and composite use, can also be used for basement and other waterproof and moisture, more suitable for the northern cold areas and structural flexibility of the building waterproof.
